TBH, when I first heard about them, I though they were going to encourage staying awake in the night and act kinda like nightmares or something of the similar.
It is definitely a lot of fun, I would suggest getting the Windows 10 version of minecraft, b/c it's Bedrock Edition and that won't crash you're laptop. However, that is provided your laptop has windows 10. Otherwise, Java is a great version and Optifine is a good mod to help your laptop run it. I've used Optifine before and can attest that id does make a difference.
